International Journal of Gynecological Cancer, 2021 Ovarian germ cell tumors derive from ovarian germ cells and account for approximately 20% of all ovarian neoplasms. Only 1–2% of ovarian germ cell tumors are called malignant ovarian germ cell tumors and constitute approximately 3–5% of all malignant ovarian neoplasms.[1][1] Yolk sac ...

KIT Is Required for Fetal Liver Hematopoiesis
Frontiers in Cell and Developmental Biology, 2021 In the mouse embryo, endothelial cell (EC) progenitors almost concomitantly give rise to the first blood vessels in the yolk sac and the large vessels of the embryo proper.

Yolk sac tumors of the ovary [PDF]
Cancer, 1970 Eighteen instances of ovarian tumor with microscopic pattern similar to that of the testicular tumors which we termed yolk sac or vitelline are presented. In the ovary, though not in the testis, this pattern has often been called “Schiller mesonephroma.” Reasons are given for our preference for the term yolk sac tumor to that of mesonephroma for these ...

Yolk sac tumors of the testis [PDF]
Cancer, 1970 The discovery of 2 yolk sac carcinomas of the mouse has established a basis in comparative pathology for the occurrence of this type of tumor in other species with yolk sacs. Grafts and tissue cultures of extra-embryonic yolk sac of the mouse have developed a clear understanding of the types of tissues one might expect in yolk sac carcinomas.

The mammalian yolk sac placenta [PDF]
Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, 2008 AbstractThere are three fetal membranes in mammals, namely the yolk sac, allantois and amnion, but only the first two form a placenta. In Monotremata (monotremes), Marsupialia (marsupials) and Placentalia (eutherians), the yolk sac transfers nutrients originating from uterine glandular secretion or the maternal blood.
